【问题描述】:
我下载了jdk 11、maven 3.6.3和Itellj Idea并导入了一个项目:
mvn clean install
但我总是得到这个错误:
Cannot resolve symbol 'SpringBootApplication'
pom.xml:

我试图删除.idea 文件夹或“无效的缓存并重新启动”,但第一种方法也没有解决问题。
有一个类似的问题Cannot resolve symbol SpringApplication,但答案并没有解决我的问题。我该如何解决?
【问题讨论】:
-
右击pom.xml并选择Maven -> Reload project
-
您在命令行构建过程中遇到错误?如果是这样,您错过了向 pom 文件添加依赖项...
-
@SpringBootApplication在编译时可用吗?你在编译范围内有相应的依赖吗?您如何尝试运行您的项目? -
@khmarbaise 在构建过程中没有错误。构建成功
-
@GiorgiTsiklauri 我编辑了我的问题并添加了 pom.xml
